摘要
比较不同耕作层深度的茭田上,新选高山茭白类型"恩茭2号"生长指标、产量指标的差异,检验耕作层深度与茭白生长指标、产量指标的相关关系。结果表明,耕作层深度显著影响"恩茭2号"的生长和产量,其中分蘗数和每墩结茭数与耕作层深度极显著相关;耕作层过浅和过深均不利于茭白生长和产量形成,在参试的耕作层深度范围内,"恩茭2号"最适耕作层深度为26.50cm,茭白产量和整齐度高,成熟早;耕作层过深,产量、净茭率、整齐度显著降低,成熟晚。
An experiment was conducted to study the relationship between tillage depths,and growth and production parameters of Zizania latifolia ＂ Enjiao No.2＂ in the mountain region of Enshi,southwestern of Hubei Province.The results show that the tillage layer depth significantly affected ＂ Enjiao No.2＂ growth and production,and the tiller number and node number were significantly correlated to tillage depths.Shallow and deep tillage layers are not conducive to the growth and production.In the depth of tillage layer in the test,the most suitable tillage depth for ＂ Enjiao No.2＂ is 26.50 cm,and the production parameters of Zizania latifoliaand uniformity are high,and become mature early.If the tillage layer is too deep,the production,cane shoot net percentage and uniformity decrease significantly,and become mature late.
